Chlordiazepoxide hydrochloride is commonly used on a short-term basis to relieve symptoms of anxiety, which include worry, fear and nervousness. These symptoms can be more acute leading up to a major or life-changing event, such as surgery.
The medicine is also most commonly used as a 'detoxification' therapy in patients going through withdrawal from acute alcoholism. It helps to reduce the effects of symptoms that tend to drive an alcoholic to drink more alcohol, such as nausea and trembling.
The prescription-only medicine is sold as a tablet or capsule and is taken by mouth. Its anti-anxiety and sedative properties affect certain chemicals in the brain and produce a calming effect. Because of its potential to be habit-forming and cause dependence, the treatment is prescribed for the shortest possible duration (typically 7 to 10 days).
The use of the medicine is restricted in certain patients, such as children under the age of six, because of safety and efficacy concerns and its potential to cause harm.
The medication is also used to treat other conditions not discussed here, such as when it is used together with clinidium bromide to treat symptoms of irritable bowel syndrome (IBS).

Chlordiazepoxide hydrochloride (Librium) is clinically approved for treating symptoms of anxiety.
The safety and efficacy of this anti-anxiety drug is well established, except for children under the age of six and elderly adults over the age of 65. The drug may severely impair alertness and physical abilities in these patients. It can also cause harm to an unborn baby and should be used with caution in breastfeeding women.
Long-term use of the medication is not recommended since it has the potential to be habit-forming and cause dependence. Patients undergoing extended therapy must be gradually withdrawn from treatment. Abrupt removal of the drug from the body may cause severe withdrawal symptoms, such as nausea, vomiting, and sweating.
Chlordiazepoxide can trigger suicidal thoughts and strange or unusual behaviors. Therefore, it may not be appropriate for patients with suicidal tendencies.
Smoking, drinking alcohol, or using other drugs that also cause drowsiness or impair alertness is not recommended during treatment with chlordiazepoxide. Similarly, patients with certain medical problems, such as liver or kidney disease, may be severely affected by the use of this anti-anxiety medicine.
For these reasons, the medication should only be used if the benefits outweigh the risks.
